    Deadly New Zealand quake hopscotched across faults

    A seemingly impossible earthquake that rattled New Zealand last November casts doubt on how well seismologists can forecast quakes involving multiple fault lines.

    Retracing the path of the magnitude 7.8 temblor using satellite and seismic data, researchers discovered that the earthquake involved at least 12 major faults and was far more widespread and powerful than predicted by seismic...

    To understand rivers, let physics be your guide

    Where the River FlowsSean W. FlemingPrinceton Univ.$26.95

    Spend an hour wandering along a river and you may wonder why the water rushing by chose this particular path over any other. While many nature writers might offer philosophical musings on the subject, Where the River Flows author Sean Fleming has physics on his side.

    Physics isn’t the lens through which most people think...

    Remnants of Earth’s original crust preserve time before plate tectonics

    Not all of the newborn Earth’s surface has been lost to time. Transformed bits of this rocky material remain embedded in the hearts of continents, new research suggests. These lingering remnants hint that full-fledged plate tectonics, the movements of large plates of Earth’s outer shell, began relatively late in the planet’s history, researchers report in the March 17 Science.

    These...

    Warming soils may belch much more carbon

    As the planet warms, carbon stashed in Earth’s soils could escape into the atmosphere far faster than previously thought. In the worst-case scenario for climate change, carbon dioxide emissions from soil-dwelling microbes could increase by 34 to 37 percent by 2100, researchers report online March 9 in Science. Previous studies predicted a more modest 9 to 12 percent rise if no efforts are...

    Earth’s mantle may be hotter than thought

    Temperatures across Earth’s mantle are about 60 degrees Celsius higher than previously thought, a new experiment suggests. Such toasty temperatures would make the mantle runnier than earlier research suggested, a development that could help explain the details of how tectonic plates glide on top of the mantle, geophysicists report in the March 3 Science.

    “Scientists have been arguing...

    Newly identified continent Zealandia faces a battle for recognition

    Lurking beneath New Zealand is a long-hidden continent called Zealandia, geologists say. But since nobody is in charge of officially designating a new continent, individual scientists will ultimately have to judge for themselves.

    A team of geologists pitches the scientific case for the new continent in the March/April issue of GSA Today, arguing that Zealandia is a continuous expanse of...

    Readers amazed by Amasia

    Saved by the Bell

    Physicists used light from stars to perform a cosmic Bell test, which verified that quantum particles were indeed “spooky,” Emily Conover reported in “Quantum effect passes space test” (SN: 1/21/17, p. 12).

    Reader George Mitchell took issue with Conover’s description of entangled photons before they are measured as having multiple polarizations at once. “We don’t know...

    Antarctic sea ice shrinks to record low

    Sea ice around Antarctica shrunk to its lowest monthly extent on record in January, the National Oceanic and Atmospheric Administration reports.

    Antarctic sea ice extent averaged just 4.04 million square kilometers, 1.19 million square kilometers below the 1981 through 2010 average. That’s 280,000 square kilometers smaller than the previous record low, set in 2006.

    The new record...

    Dual magma plumes fueled volcanic eruptions during final days of dinosaurs

    Not one but two rising plumes of magma from deep within the Earth fueled the titanic volcanic eruptions that marked the final days of the dinosaurs, new research suggests. The Deccan eruptions in what is now India, some scientists argue, helped wipe out most animal and plant species around 66 million years ago, including all nonbirdlike dinosaurs.

    The geologic source of that volcanism...

    Oxygen flooded Earth’s atmosphere earlier than thought

    The breath of oxygen that enabled the emergence of complex life kicked off around 100 million years earlier than previously thought, new dating suggests.

    Previous studies pegged the first appearance of relatively abundant oxygen in Earth’s atmosphere, known as the Great Oxidation Event, or GOE, at a little over 2.3 billion years ago. New dating of ancient volcanic outpourings, however,...
